The Labor Department reported that the consumer price index edged up 0.1 percent in May. The core rate, which does not include volatile food and energy components, gained 0.2 percent.

In addition, the so-called Beige Book report released by the Federal Reserve indicated a slightly different take on the state of the economy. The report, a regular anecdotal account on the regional economies around the country, found that while solid economic growth continues in most areas, almost all of the 12 federal districts reported a "slowing" in the pace of growth and a "worsening" increase in pricing pressure.
"I think the Fed will be on hold for June," said Mickey Levy, chief economist at Banc of America Securities. "There are clear signs that the economy is slowing down."
Economist Peter Kretzmer of Banc of America says the slowed economy will not "turn into a recession. Businesses are responding efficiently by slowing down production and reducing the number of hours worked," he said.
Yet some believe the inevitable slowdown will hurt corporate profits. "The economy is going to slow down, and that will cause earnings growth to decelerate," said Richard Cripps, a market strategist at Legg Mason.
"There are several cross currents in the market," said Cripps, adding that as the economy progresses, rising oil, commodity and labor costs, along with a weaker dollar, will each put a drag on overall growth.
